Definitions
- a further object of the present invention is to use an electrochemical autothermal reformer to produce pure hydrogen- from a hydrocarbon fuel for use in a fuel cell to generate electricity.
- an EATR (electrochemical autothermal reformer) 200 includes an ATR (autothermal reformer) 210 joined to an anode supply region 230 by a membrane layer 220.
- the membrane layer 220 is a mixed ion conductor.
- An electrochemical autothermal reformer combines the principles of electrochemical hydrogen separation and autothermal reforming in tandem. The purpose of the electrochemical autothermal reformer is to effect the selective removal of hydrogen from the autothermal reforming region of the EATR so as to drive the reforming reaction to completion while separating the hydrogen gas for use on the anode side of a fuel cell.
- the gas mixture enters heat exchanger D1/D2 at node 16 where it is heated.
- the gas mixture then enters heat exchanger A1/A2 at node 18 where it is further heated before entering the anode supply region 230 of EATR 200 at node 19.
- the gas mixture is thus preferably heated to near the operating temperature of EATR 200.
- the presence of the carrier gas allows the hydrogen partial pressure at node 19, and therefore in anode supply region 230, to be low with respect to the hydrogen partial pressure in ATR 210, which is necessary for hydrogen to cross the membrane layer 220 from ATR 210 into anode supply region 230 by virtue of a hydrogen partial pressure or concentration gradient.
- Air from node 23 is fed into the fuel cell cathode section 130 at node 24.
- the air in cathode section 130 provides the oxygen required for the functioning of fuel cell 100.
- the cathode air is exhausted from the cathode section 130 at node 25, thus removing water vapor which is produced from the cathode section 130 by the action of the fuel cell 100.
- the air passing through cathode section 130 also provides some cooling effect for fuel cell 100.
- Water from cathode section 130 is optionally sent to the boiler 160 via node 30 and pump 270 to augment the water provided to boiler 160 from condenser 280.
- Pump 270 is preferably a circulation pump unless ATR 210 is being run at high pressure as described above.
- a condenser (not shown) is optionally used at node 25 as necessary.
- having a higher hydrogen partial pressure in ATR 210 relative to anode supply region 230 permits hydrogen to cross the membrane layer 220 from ATR 210 to. anode supply region 230.
- hydrogen partial pressure is higher in anode supply region 230 than in ATR 210, hydrogen crosses the membrane layer 220 in reverse from anode supply region 230 to ATR 210.
- Monitoring a temperature of the exhaust from burner 260 at node 14 exploits this fact. If there is low power demand on fuel cell 100, hydrogen is not consumed by the anode section 1 10 and the hydrogen partial pressure in anode gas loop 300 increases.

Abstract
La présente invention concerne une centrale à pile à combustible comprenant un dispositif de reformage autothermique et électrochimique (EATR) (200) fournissant de l'hydrogène à la pile (100) à combustible. Le dispositif EATR comprend une zone de reformage autothermique (210), une zone d'alimentation anodique (230), une membrane (220) de conducteur à ions mixtes, une membrane métallique ou une couche membranaire (220) d'un alliage métallique séparant les zones de reformage autothermique et d'alimentation anodique. Une boucle de gaz (300) d'anode située entre la zone d'alimentation anodique du dispositif EATR et un compartiment ou une partie (110) anodique de la pile à combustible fait circuler un mélange d'hydrogène et d'un gaz porteur entre les deux zones. Le gaz porteur assure une bonne commande des pressions partielles de l'hydrogène dans les deux zones. Des échangeurs de chaleur exploitent une différence de température de fonctionnement entre le dispositif EATR et la pile à combustible, et permettent efficacement certaines fonctions de chauffage et de refroidissement dans la centrale.
